Maintenance Release: DHTMLX Gantt 9.1.3, Scheduler 7.2.13, Kanban 1.7.2, and RichText 2.0.5

The success of web development tools largely depends on their ability to evolve continuously and remain reliable over time. It means that vendors must remember about continuous refinement, not just new features. That’s what we do at DHTMLX, regularly releasing bug fixes and minor enhancements that strengthen the stability and consistency of our JavaScript UI components. In March, we rolled out patch versions of Gantt, Scheduler, Kanban, and RichText Editor. Check out the details below.
